HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 45720 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 918, 45720 is 18 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 918, 45720 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 918, 45720 is 18.
HCF(918, 45720) = 18
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 918, 45720 is 18.
Step 1: Since 45720 > 918, we apply the division lemma to 45720 and 918, to get
45720 = 918 x 49 + 738
Step 2: Since the reminder 918 ≠ 0, we apply division lemma to 738 and 918, to get
918 = 738 x 1 + 180
Step 3: We consider the new divisor 738 and the new remainder 180, and apply the division lemma to get
738 = 180 x 4 + 18
We consider the new divisor 180 and the new remainder 18, and apply the division lemma to get
180 = 18 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 918 and 45720 is 18
Notice that 18 = HCF(180,18) = HCF(738,180) = HCF(918,738) = HCF(45720,918) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 918, 45720?
Answer: HCF of 918, 45720 is 18 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 918, 45720 using Euclid's Algorithm?
Answer: For arbitrary numbers 918, 45720 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
